Abstract

See full text

A rotary tobacco treatment cylinder includes an elongate hollow cylinder arranged to rotate about its longitudinal axis and disposed substantially horizontally or inclined by a small angle to the horizontal, a series of elongate paddles extending longitudinally within the cylinder and extending generally towards the longitudinal axis from the inside surface of the cylinder, the paddles serving to convey material to be treated from a lower position within the conveyor and around one side to an upper discharge position. Each of the paddies has a proximal portion extending at a first angle being a right angle to the tangent at the root of the proximal portion or an angle less than a right angle at the loaded side of the paddle, and a distal portion which is inclined to the proximal portion at a second angle, which is less than the first angle, to form a tip. A major part of the tip considered longitudinally is of a length (viewed axially of the cylinder) less than half the length of the proximal portion. The angle of the tip of each paddle to the tangent at the root of the proximal portion is such that at a predetermined release point the tip is at the angle of sliding, the surface of the tobacco charge just contained by the top being at the angle of repose.
